RVKRED06 - Background jobs for checking
blocked credit management.
If an order is no longer outside the horizon as defined in the dynamic
credit check, (i.e. it is INSIDE the horizon) it can cause existing "good"
orders to block. If you run this job every night, if you have your horizon
set for 1 month it can cause a lot of blocks at beginning of month. Try
to use 'W' for weekly horizon status.
